hating-gas; and it consists in the novel ar-.

rangement and combination of parts more fully set forth in thespecification and pointed out in the claims.

In the drawings, Figure 1 is a combined section and elevation of theapparatus, the f walls of the tank being broken away. Fig.

2 is a similar view to Fig. 1, but in a plane is a detail at rightangles thereto. Fig. 3 showing the manner of adjusting the floats, andFig. 4 is an elevation of a modified form of float-pipe.

The object of our invention is to construct an apparatus for themanufacture of gas.

from volatile liquid hydrocarbons, the device being designed for thespecial view of" insuring uniform results in the matter of thegeneration of the gas irrespective of the quantity of hydrocarbontreated.

In detail the invention may be described as follows:

Referring to the drawings, 1 represents a closed tank or generator,preferably submerged below the surface of the ground, said tank beingdivided into two compartments by a partition 2, the base of the latterbeing cut away, leaving a communicating passage 3 between the twocompartments. Oommunicat ing with the smaller of the compartmentsthrough the roof of the tank is an air-pipe 4, to which is coupled, bymeans of a T 5, the air-supply pipe 6, leading to any suitable airpump,(not shown,) the top of the pipe 4 being closed by a cap 7. Locatedwithin the pipe 4 and passing also through the roof of the tank andprojecting a short distance into the latter is a guide-tube 8, open atboth ends, the upper end extending to near the cap 7. Adapted to playwithin the guide-tube is a float-pipe 9, open at its upper end, butclosed at the bottom, said pipe 9 having lower laterally-projectingdischarge-tubes or spraypipes 10, closed at their ends, but providedwith upper peripheral openings 11 f0r the es cape of the air forced intothe pipe 4. The pipe 9 is kept floated on top of the liquid in the tankby means of two cylindrical hollow floats 12 12, pivotally secured tothe pipe 9 by means of links 13 13 on either side of the tubes 10. Thedistance between the floats is regulated by means of an adjusting-screw14, over whose right and left hand screw-threads are respectivelyadapted to travel the terminal loops 15 of the connecting-arms 16,secured to the floats. It is desirable under all circumstances to retainthe discharge-openings 11 a slight but constant distance below thesurface of the liquid in the tank; but as the specific gravities ofdifferent liquids operated on differ it is apparent that the floatedpipe 9 would sink to different levels according to such specificgravities. By varying the distance between the floats, however, thedepth of submergence of the pipe 9 may be kept constant, for it isobvious that by turning the screw 14 in a direction to cause the rods 16to approach (see dotted lines, Fig. 3) the effect would be to bring thefloats closer together and depress the same, and hence tend to eitherraise the pipe 9 in a liquid of constant specific gravity or retain thesame at the same level in a liquid of lower specific gravity. So, also,should the gravity of the liquid be greater than the floats had been setfor, by separating the floats the pipe 9 will sink to the proper depthto bring the openings 11 to their desired position below the surfacelevel of the liquid. Leading also to the smaller of the compartments isa fillingtube 17, having a cap 18, and communicating likewise with saidcom partment is a vent-pipe 19, the base of which is coupled by a pipe20 with the top of the large compartment, the vent-pipe serving to allowfor the escape of the air when the tank is being filled through the tube17. The vent-pipe 19 is closed by a plug or stopper (not shown) afterthe tank is filled to prevent any escape of the gas generated in thetank after the apparatus is once started. Leading from the air-supplypipe 6 at a convenient point is a shunt or branch pipe 21, controlled bya needle-valve 22, os-

tablishing communication between the pipe 6 and the top of the smallercompartment of the tank. 23 represents the gas-deli very pipe. The upperends of the pipes are protected by a hood or box 24.

The Operation of the device is as follows: By means of the air-pump (notshown) air is forced through pipe 6 and T 5 into pipe 4, the aircirculating, as seen by the arrows, upward through the space around thetube 8, (which space is closed at the bottom by the annular plug whichsupports the tube 8 and which is inserted between the said tube and thepipe 4,) thence down said tube into the float-pipe 9, and out throughthe openings 11 of the spray-pipes 10, the force of the jets of airdisintegrating the oil and converting it into gas, which is forcedthrough the pipe 23 to the pointpf consumption. By maintaining the pipes10 at a slight and constant level below the surface of the liquid theamount of gas generated will be constant for a given pressure andtemperature of air forced into the same. A slight percentage of air willfind its way above the liquid from the space between the tube 8 and pipe9, as seen by the arrows, this slight amount insuring the admixture of aquantity of oxygen sufficient to effect perfect combustion of the gasdisengaged from the surface of the liquid. Should it be desirable to mixa greater percentage of air above the liquid, the needle-valve 22 may beopened, in which event a part of the aircurrent will be diverted andrush into the tank through the branch pipe 21.

In case where it be not desirable to permit any airto mix above theliquid we extend the guide-tube 8 (see Fig. 4) below the normal level ofthe liquid and form a bend 25 in the float-pipe 9, providing the freeend of the arm of the bend with spray-pipes 10 and floats 12' in likemanner as in the foregoing description, the adjusting-screw in this casebeing above instead of below the spray-pipes 10. In this modification noair can possibly enter the tank except that which escapes through thepipes 10.

It is apparent, of course, that other changes may be made in the presentapparatus without departing from the spirit of our invention. Thecharacter of liquid hydrocarbon is immaterial, and the same may begasoleue, kerosene, ligroin, naphtha, and the like.

The object of the partition 2 is to confine the agitation of the oil andthe generation of the gas to but one compartment and concentrate thesame toward the delivery-pipe, the other compartment constituting thefeed for the gas-generating compartment.

Having described our invention, what we claim is 1. In a gas-makingapparatus, a suitable closed tank or generator, an air-pipe leadingsuitable devices for floating the float-pipe on top of the liquid in thetank, substantially as set forth.

2. In a gas-making. apparatus, a suitable closed tank or generator, anair-pipe leading from the roof thereof, and closed at the top, aguide-tube confined within the air-pipe and open at both ends,afloat-pipe loosely playing in the guide-tube closed at the bottom butopen at the top, spray-pipes carried at the lower end of the float-pipe,closed at their outer ends but having upper peripheral openings, anair-supply pipe communicating with the air-pipe above the tank, agas-delivery pipe leading from the upper portion of the tank, andsuitable float-cylinders for the floatpipe, substantially as set forth.

3. In a gas-making apparatus, a suitable closed tank or generator havingtwo communicating compartments, an air-pipe projecting from the roof ofone of the compartments, a guide-tube in the air-pipe, vent-pipesleading from both compartments, a filling-tube located adjacent to theair-pipe, a float-pipe loosely playing in the guide-tube, spray-pipescarried at the lower end of the float-pipe, an air-supply pipe toppingthe air-pipe above the roof of the tank, a gas-delivery pipe, avalvecontrolled shunt leading from the air-supply pipe to thecompartment with which the airpipe communicates, and means forregulating the depth of submergence of the float-pipe in the liquidconfined in the tank, substantially as set forth.

4:.

In testimony whereof we affix our signatures in presence of twowitnesses.
